Fast, clean concrete lifting in Kansas City, MO.
Most projects take hours, not days, and cost 50–70% less than replacement.
Uneven slabs create trip hazards, drainage problems, and surface damage that worsen over time.
Concrete lifting restores a level surface by raising the slab from below. It’s fast, clean, cost-effective, and avoids concrete replacement.
If your driveway, sidewalk, patio, porch, steps, garage floor, concrete floor, or pool deck in Kansas City, MO is sinking or uneven, replacement is not your only option. Foamjection provides professional concrete lifting and leveling in Kansas City using high-density polyurethane foam.
Our polyurethane concrete leveling process—also known as polyjacking or slabjacking—lifts settled concrete from below, fills voids, and restores support without demolition. Most residential projects in Kansas City are completed in hours, not days, and surfaces are often ready for use the same day.
Our foam concrete leveling process avoids demolition, hauling, and new concrete costs — delivering a long-lasting fix at a fraction of the price.
Precise injection points and lightweight equipment allow most projects to be completed in hours, not days, with minimal disruptions.
Built for Long-Term StabilityHigh-density eco-friendly, polyurethane foam fills voids, strengthens weak soil, and resists water and erosion to help prevent future settlement.

Inject High-Density Polyurethane FoamThis is the core of polyurethane concrete lifting — the foam expands beneath the slab, fills voids, stabilizes loose soils, and delivers a controlled slab lifting process.
Patch & Use the Same DayOnce the slab reaches the correct height, holes are patched and the area is often ready to use within hours.
My driveway looks brand new after the slab lifting — and it was done in one afternoon.
Polyurethane concrete lifting saved us thousands compared to replacement.
Fast, clean, and no damage to our landscaping. Foam lifting works exactly as they explained.
Foamjection fixes sinking concrete by injecting high-density polyurethane foam beneath the slab. Small holes are drilled, and the foam is injected into weak or empty areas under the concrete. As the foam expands, it fills voids, stabilizes the soil, and gently lifts the slab back into position—all without removing or replacing the concrete. Learn more about the full process.
Concrete usually sinks because the soil beneath it weakens or shifts over time. This can happen due to poor soil compaction during construction, water erosion, drainage issues, freeze-thaw cycles, or washout around the slab. When the soil loses strength, the concrete no longer has solid support and begins to settle unevenly.
Foamjection uses high-density polyurethane foam to raise, level, and stabilize concrete. The material starts as a liquid and is injected beneath the slab, where it expands to fill hidden voids, strengthen weak soil, and gently lift the concrete back into position.
Once cured, the foam becomes a durable, moisture-resistant solid that does not break down in wet conditions or add unnecessary weight to already unstable soil. Because the foam is lightweight yet strong, it helps support the slab without contributing to future settlement.
Compared to traditional mudjacking materials, polyurethane foam requires fewer and smaller injection holes, making the repair far less noticeable. The process is also cleaner, faster, and more precise, with most surfaces ready for use the same day.
Foamjection’s polyurethane foam is designed for long-term performance and environmental responsibility. It contains renewable content, does not leach harmful chemicals into the soil or groundwater, and eliminates the need for concrete tear-out and landfill waste. By lifting and stabilizing existing concrete instead of replacing it, homeowners get a lasting repair that’s better for their property — and the environment.
Mudjacking uses a heavy cement-based slurry to lift concrete, while polyurethane lifting uses lightweight expanding foam. Foam requires smaller holes, adds very little weight to the soil, cures faster, and offers more precise control during lifting. Because of this, polyurethane lifting is often cleaner, faster, and longer-lasting than traditional mudjacking.

Residential Concrete Leveling / Commercial Concrete Leveling
Yes, in many cases. Polyurethane foam lifting is a controlled process that gently raises the slab from below. Because the slab itself is not removed or broken apart, decorative and stamped concrete can often be lifted while preserving its appearance. Check our concrete lifting work
Yes. Foamjection is commonly used for interior concrete floors in homes, warehouses, factories, and other buildings. The equipment is compact, and the process does not require large machinery or demolition, making it ideal for indoor applications.
Large voids are one of the main reasons concrete settles. Foamjection’s expanding foam is designed to flow into empty spaces beneath the slab, filling those voids and restoring support. This not only lifts the concrete but also stabilizes the soil to help prevent future settlement. Know more
The cost depends on several factors, including the size of the slab, how far it has settled, and the condition of the soil underneath. In most cases, concrete lifting costs significantly less than full replacement. The best way to get accurate pricing is through a free quote.

After you request a quote, we will schedule a time to stop out and review your concrete issue, assess whether lifting is the right solution, and provide clear pricing and next steps.
Warranty coverage varies by project, but Foamjection focuses on long-term stabilization—not just lifting the slab. We will explain warranty details clearly before work begins so you know exactly what’s covered.
For many homeowners and businesses, yes. Concrete lifting can save up to 70% compared to replacement, avoids demolition, reduces downtime, and keeps existing concrete out of landfills. Replacement is sometimes necessary for severely damaged slabs, but lifting is often the smarter first option.
Most concrete lifting projects are completed in just a few hours. The exact time depends on the size of the slab and the complexity of the job, but it’s much faster than removing and replacing concrete.
In most cases, surfaces are ready to use almost immediately after lifting. Polyurethane foam cures quickly, so there’s typically no long waiting period before walking or driving on the concrete.
After lifting, the slab will be level and stable. The small injection holes are patched and blended to be as discreet as possible. While patches may remain visible up close, the surface is far less noticeable than cracked or sunken concrete.
No. The process is clean and minimally invasive. There’s no heavy demolition, no large equipment tearing up your yard, and no extended curing time like with replacement.
Typically, no. Foamjection uses compact equipment and hoses that allow technicians to reach the slab without driving heavy vehicles across your lawn or landscaping.
Basic maintenance helps extend results, such as sealing joints, managing drainage, and making sure downspouts direct water away from concrete. Your technician can provide guidance based on your specific situation.
Yes. The polyurethane foam used by Foamjection is engineered for safety, and durability and moisture resistance. It does not leach harmful chemicals into the soil or groundwater. And it adds very little weight to the soil, helps reduce waste by extending the life of existing concrete, and is manufactured with up to 40% renewable content.
